KTA Thermistor & RTD Sensor
Brand: KeleThe Kele KTA Series All-Purpose Thermistor and RTD Sensors provide remote temperature sensing for building automation systems and mechanical equipment room instrumentation.
The active sensing element is made of a highly stable thermistor material or platinum RTDs.
The KTA Series sensors are rugged, point-sensitive waterproof sensors featuring a 9" (22.8 cm) 304 stainless steel probe and brass fitting.
The brass fitting has a 1/2" NPT male thread.
The sensors are supplied with two 1/2" locknuts for easy installation in handy boxes (or other enclosures with 1/2" knockouts).
Features- Wide selection of thermistor and RTD curves
- Tip sensitive for precise temperature response
- All metal construction with 304 stainless steel probes
- Easy to mount to duct, wall, or back box
- Waterproof probe
